To all whom it may concern:

Be it known that I, NICOLAS HENRY Gnos- SELIN, Fils, a citizen of France, residing at Sedan, France, have invented certain new and usefullmprovementsinGig-Mills,(whichhave been patented to me in France November 25, 1887, No. 187,208; in Belgium March 7, 1888, No. 80,913; in Germany July 27, 1889, No. 55,784; in Great Britain April 11, 1888, No. 5,394; in Switzerland February 19, 1889, No. 501; in Italy December 14, 1888, No. 24,592- 408; in Spain January 24, 1889,No. 9,144; in Austria-Hungary February 25, 1889,N0.9,132 and No. 23,070, and in Russia February 20 and March 4, 1889, No. 11,867,) of which the following is a specification.

Myinvention relates to gig-mills of the character described in my Letters Patent, No. 377,15l,dated January 31, 1888thatis to say, to gig-mills which comprise a drum around which are arranged teaseling or card rollers having a variable rotary movementindepen dent of the drun -and one characteristic fea ture of my invention is the arrangement of the working or card rollers, which preferably are all teaseling-rollers, by which they are mounted on a drum in such a way that one series of said rollers turns in a reverse direction to the other series. By this arrangement when the rollers are all teaseling-rollers the goods can be teaseled or dressed simultaneously both in the direction of and against the nap. This teaseling operation in both directions is indispensable in the treatment of many characters of goods. lleretofore this result has been attained only by the use of several drums or by submitting the cloth more than once to the action of the same drum, which necessitated the turning of the cloth end to end for each action of the drum.

My arrangement not only avoids the use of two drums, but also obviates the loss of useful effect which arises therefrom in the case of felted fabrics and of cloth where only a short thick nap is desired, when as in existing methods teaseling in two directions is not simultaneous.

My invention, moreover, consists in arranging the rollers in alternating series-that is to say, so that the adjoining teaseling-rollers turn in opposite directions. Another advan tage arising from the arrangement of the reversely-turning rollers, and especially the arrangement in alternating series just referred to, is that they tend to neutralize each others tendency to produce a drag on the fabric treated. The drum does not, therefore, drag said fabric in either direction, thus enabling me to dispense in a great measure with the usual dragging-rollers, which is an important advantage. Another advantage arising from this arrangement is that I am thereby enabled to utilize the entire Working surface of the drum for card-rollers,inasmuch as the rollers which work against the nap may be utilized as guide-rollers for regulating 'the pressure of the fabric on the drum or they may act both as guide-rollers and teaselingrollers.

Inasmuch as the cards in the two series of teaseling-rollers point in opposite directions, it becomes necessary to have separate strippers, which act each only on one series. My invention, therefore, also consists in arranging one series of teaseling-rollersfor instance, those which act against the nap-at agreater distance from the center of the drum than the other series, in connection with two strippers for cleaning the cards of the teaselingrollers, one exteriorly located and the other arranged in the interior of the drum. Bythis arrangement both series of teaseling-rollers are stripped of the flock adhering to them as they pass the strippers, and the strippers of the one series do not interfere with the rollers of the other series.

My invention also consists in other devices of construction to be set forth in the specification and claims; but to enable those skilled in the art to carry out my invention I will now particularly describe the same, reference being had to the accompanying drawings, in which Figure 1 is a side elevation of the gig-mill embodying my invention; Fig. 2,a plan of the working-rollers; Fig. 3, a vertical transverse section of the drum carrying the rollers; Figs. 4 and 5, a partial front elevation and a partial vertical section, respectively, of a machine, showing a modification of certain features of my invention; Fig. 6,an elevation of a machine embodying still another modification; Fig. 6, a detail thereof, and Fig. 7 a vertical transverse section of still another form of driving mechanism.

Referring now to Figs. 1, 2, and 3, it will be noted that I provide a drum A, consisting of a shaft 17 and two heads or disksj, and nappingrolls having journals turning in bearings of the heads. The drum may ca ry any desired number of working or teaseling rollers-in the present instance, fourteen, of which seven, marked T, work against the nap and seven, marked T work with the nap. The drum A derives the requisite action to feed forward the cloth to be treated by any suitable meansin the present instance, as shown in Fig. 1, from pulley which may be on the driving-shaft, by a crossed belt 6 passing around said pulley G to the pulley (1* on the shaft a. of the drum A. On the shaft 0, driven by gears 8 8 (shown by dotted lines in Fig. 1) from the shaft of the pulley G are mounted thetwo pulleys O and C of different diameters, for a purpose presently to be described.

The pulley O carries the crossed belt a, which runs thence over the pulleys B of the rollers T, which work against the nap. The smallerpulley O carries the uncrossed belt 0 which runs over the pulleys B of the rollers T which work with the nap and over the pulley 0*.

The arrangement of the pulleys B and B and the rollers T and T will best be understood from Fig. 2, where it will be seen that the said pulleys B and B are equal in diameter to the rollers T and T It will also be noted that the pulleys B are within the frame of the drum and the pulleys B are in the usual manner arranged outside the frame.

It follows from the fact that the diameters of the pulleys B and B are equal to those of the rollers Tand T that when the shaft 0 is stopped the backward development of the card-rollers T and '1 will be exactly equal to the forward development of the drum-that is, they will not act on the cloth. This is the minimum of effect.

When the shaft 0 is driven in the direction ofthe arrow 1 in Fig. 1, the backward motion of the rollers T, by virtue of the crossed belt a, will be accelerated and the rollers T by virtue of the uncrossed belt 0 will have their backward motion diminished. The various speeds of theshaft may be produced by any known means.

It will be seen by referring to Fig. 1 that the driving-pulley (J' for actuating the crossbelt 0 and rollers T, that act against the nap, is larger than the driving-pulley O actuating the belt 0 and rollers T working with the nap. The object of this arrangementis to compensate for the onward travel of the fabric, which diminishes the action or effect of the rollers that work with the nap and increases such action or effect of the rollers that Work against the nap. On the same shaft with pulley O is a pulley O of smaller diameter and a larger pulley C, from which a belt 0 passes to the pulley O on whose shaft is a smaller pulley C The pulleys O and O in conjunction with the drum A, act to slowly feed forward the cloth D, which is guided in its movements bya series of idlers I and travels in the direction indicated by the arrows 2.

. Where teaseling-rollersin two sets working in opposite directions are employed, it becomes necessary to provide two strippers, one for each set of teaseling-rollers In the construction illustrated in Figs. 1, 2, and 3 I provide a rotary exterior stripper F of the old construction and an interior stripper H of novel construction. In order to enable each stripper to act on its series of teaseling-rollers and not interfere with the ot-herset, the-rollers T are placed at a greater distance from the center of drum A than the teaseling-rollers T The former are thus acted upon only by the exterior stripper F, deriving its rotary motion through a beltf, acting on a pulley F and running thence over a pulley on the drum A.

The rollers T are stripped by the interior stripper H, which consists, essentially, of a card-plate having straight teeth, whose ends lie in a curve adapted to the path described by the rollers T The said stripperf'H is attached to a hanger H depending loosely from V 7 the shaft of the drum A, and may be adjusted inheight by means of the binding-nuts a C0 on its shank a as shown. Instead of the card-plate a depending brush may be employed. Theinterior stripper is held in proper position by its weight, and as the rollers T which act with the nap, successively come into contact with the stripper and are cleaned the flock or waste withdrawn from the cards of the teaseling-rollers falls below the drum through the spaces between the rollers.

Various modifications may be effected without departing from the spirit and nature of my invention. For example, instead of having the rollers which work with, the nap alternate with those which work against the nap I may place two or three or more rollers working with the nap between two working against the nap, and vice versa, the particular arrangement depending upon the nature of the fabric to be treated. Again, it may be useful in some cases to actuate the oppositely-revolving working rollers by belts which do not run' wheels 0/: 00', which are removably mounted upon the shafts for the purpose of interchangeability to vary the relative speed of the two shafts and for removability to cause one of the shafts to stop when desired.

If desired, there may be two belts for each set of napping-rolls, so arranged at opposite ends of the drum that there is always at least one belt operating on such rolls. Thus these two belts 0' 0 Fig. 6, perform the same office; but as one belt passes to the right and the other to the left of the guide-pulley M one of the pulleys B at one end or the other of a roll passing from beneath drum M to beneath drum M will be in contact with a belt. In like manner the two belts 0 c difierently arranged at opposite ends of the drum, as indicated by dotted lines, serve to insure a contact of one pulley or the other of pulleys B of each roll with one of the belts at all times. This arrangement is more expensive than that first described, but it offers several advantages. It admits of making the operation of teaseling against the nap independent of teaseling with the nap.

WVhen one of the toothed wheels-say the wheel 9(3'--iS removed, which may be done by slipping it from the shaft to which it is secured, as by a set-screw t the action of the one set of teaseling-rollers T immediately ceases, the other set T only, which is actuated from the pulley (J connected with the source of power, revolving. This is of advantage for certain fabrics. Motion is imparted from the shaft of the pulley (3 through the medium of a pinion g of said shaft gearing with a toothed wheel '0 on the shaft of the pulley 0 as indicated by dotted lines in Fig. 6. When the toothed wheels are exchanged for others of difierent relative diameters, the working energy against the nap is modified in its relation to the working energy with the nap. This is also a very useful feature in treating certain classes of fabrics. The two shafts O 0 thus ofier greater facility in the regulation of the machine, especially for manufacturers who produce goods of different kinds. Other known means may be employed instead of the toothed wheels to connect the shafts C C.

In the arrangement illustrated in Fig. 7, and which is useful for some purposes, the outer set of working or card rollers T, which have been described as those working against the nap, are driven by a fixed strap 0' 0', one end of which is attached to the frame and the other end provided with a screw and nut C whereby its tension is regulated. It is necessary in order to cause these card or working rollers to work against the nap to make the diameter of their pulleys B greater than that of the rollers themselves, and the difference should be in proportion to the forward speed of the fabric. Thus it will be understood that if the fabric is required to advance thirtysix feet per minute the rollers should turn backward the amount that the drum turns forward less thirty-six feet. The other rollers T which work with the nap, are driven in the way first described by a belt c It will be noted, also, that in this modification I have shown the card or working rollers T as provided with straight teeth, so that they will act only as drawing-rollers for maintaining and regulating the tension of the fabric for the other working or teaseling rollers. This modification is useful when the goods do not require simultaneous teaselin gin two directions.

It will be noted that the term working or card rollers wherever employed in this specification and claims is not confined to teaseling-rollers, although it includes them, and includes such drawing-rollers as just described. Instead of being fitted with cards having straight teeth, these rollers T may be covered with plush, emery, or other material to which the fabric has a tendency to adhere.

In Figs. 4. and 5 I show another form of internal stripper, which is adapted to fabrics that lose much flockin the teaselin g operation, and which consequently require a more energetic stripping device. It will be observed that I here employ a circular rotary stripper H, similar to the external stripper, and which is loosely suspended, like the stripper-plate H, (shown in Figs. 1, 3, and 7,) before described. A toothed wheel 1 keyed on shaft o of drum A, meshing with the pinion h, keyed to .the shaft of the rotary stripper H, which is kept in its downward position by its own weight, imparts the necessary rotary motion to the stripper. The cloth can be made to entirely or partially surround the drum A, according as it is or is not carried over the guide-drum I.
